Han Solo, known only as Han until being given the surname Solo, and formerly known as Cadet 124-329 while serving as an Imperial cadet, was a human male smuggler. He rose from an impoverished childhood to become captain of the Millennium Falcon, a leader in the Alliance to Restore the Republic and an instrumental figure in the Galactic Civil War during the reign of the Galactic Empire. Although he did not believe in the Force controlling his destiny, Han came to believe in the cause of galactic freedom, joining Jedi Luke Skywalker and Princess Leia Organa in the fight for the Rebellion. Following the war, Han and Leia welcomed a son, Ben Solo, who became Kylo Ren after being lost to the dark side of the Force. Although their relationship foundered, Leia hoped that Han, as his father could find a way to break the dark side's hold on Ben. Han Solo became legendary across the galaxy as both a smuggler and war hero of the Rebellion.
